Mix the fat-blasting, cardio-friendly principles of Pilates with the fun and excitement of dance in these three low-impact workouts from fitness pro Denise Austin. In the 30-minute "Cardio Dance," Austin introduces an easy-to-follow series of shakes, shimmies and twists, then follows with the 10-minute Pilates-centric workouts "Pilates Standing" and "Pilates Mat."
